Launch Window

A launch window refers to a specific period during which a spacecraft must be launched to achieve its intended mission, such as reaching a destination or aligning with another celestial body. This timeframe is determined by various factors, including the positions of the Earth, the target, and the spacecraft's trajectory. If the launch doesn’t occur within this window, the mission may need to be postponed, as the alignment or conditions may change, making it impossible or less efficient to reach the desired destination. Proper timing is crucial in space exploration to ensure mission success.
